(01. 235-59) Theinvention relates to a printing adding machine, with column countersarranged on the paper carriage.

Printing adding machines have been provided;-

with column counters, which are arranged on the paper carriage, in orderthat these machines can execute column work as this can be performed intypewriting calculating machines: The advantage of typing text however,is lost in such machines. The typing of text is particularlyindispensable in pay and invoice matters.

This disadvantage is obviated according to the invention in which theprinting adding machirie is combined with a typewriting machine, bothmachines being advantageously arranged side by side.

Accordingto a preferred form, both machines are provided with a commonpaper carriage, .which carries the column counters.

In the drawings one example of the invention is represented.

General description The typewriting machine, 2, is arranged at the righthand, and the adding machine, 3. at the left hand of a common base plateI (Fig. 1).

The typewriting machine, 2, is provided with the usual letter typingkeys, 4, and figure typing keys, 5, which letter and figure typing keysare connected in a known manner with the type levers, '6, (Fig. 2).Underneath and in front of the letter keys, 4, are arranged Incalculating keys, 1.

with the numbers 0 to 9 for the adding machine,

3. The levers, 8, of the calculating keys, I, (Fig. 3) at their rearends are mounted on bearings at, 9, so as to be capable of oscillation,and by means of a. pin and slot connection, I 0, ll, they are connectedto setting levers, ii, for the stop carriage, l5, of the adding machine,3. The levers project towards the left and are pivotably mounted inbearings on bearing blocks, [3, (of any suitable type) attached to themachine frame in any suitable manner. If a calculating key,1, isdepressed, the lever, i4, connected with the key lever, 8, is swung inthe clockwise direction and by means of the upwardly projecting rearend. 16, of the same, the corresponding stop, I1, is set in the stopcarriage, i5, and is held by means of aspring, l8, in this workingposition. The stop carriage, i5, as is evident in Figs. 2 and 3, isslidably arranged, by means of rollers, IS, on two rails, 20 and 2i,fixed in the machine, and for the remainder is arranged similarly to thestop carriage represented and described in Patent Specification No.1,329,028.

. Against the stops, ll, set as above described the feeler rods, 23,(Fig. 3) are released on the operation of the machine by means of acrank handle (not shown) or through the depression of a motor key, 22,(Figs. 1 and 2), whereby under the action of the springs, 25, acting nthe type printing rods, 24, and through the pin and slot connections,26, 21, and the sectors 29, carrying the toothed segments, 28, 28a and28b, and the pin and slot connection, 30, 3i, the feeler projections,32, of the feeler rods are carried against the set stops, i1, wherebythe driving sectors, 29, and the toothed segments, 28, 22a.

and 28b, rotatably mounted on it, are YOliflifid duce this value intothe totalizers. By means of the slots, 23a and-23b, in the feeler rods,23,

into which project suitable screws, 23c and 23d,-

arranged in any suitable manner on the machine frame, the feeler rodsaredisplaceable in the direction of the arrow 1.

As soon as the type-printing rods 24 have been raised by theirsprings 25in accordance with the amount set up by means of the calculating keys I,the hammer mechanism-which will be described later on in a more detailedmanner-is operated to thrust the types against the platen 33 which iscommon to the adding machine 3 as well as the typewriting machine 2.

Pin carriage escapement In the operation of one of 'the calculatingkeys, 1, the rearwardly directed part of the lever, l4, (Figs.3 and 13)acts with its upwardly directed edge, l4a,'on a yoke, 20x, swingablymounted at the points, 200. and Mo, on the running rails, 20 and 2|. Theyoke, 20:, at the part, 20c, connecting the limbs, 20b and. Zlb, isdownwardly angled and is provided with teeth, 20d, between which therearwardly directed levers, H, which at their free ends are bent towardsA the left, (Fig. 2), are capable of projecting and in this way are.simultaneously .guided. yoke, 20x, now,.on the striking of one of thecalculating keys, I, can act in any suitable manner on the nose'20F ofthe part 20G of the shift lock 20A, (Figs. 3,8, 9, and 13), for instancethrough the intermediary of a lever 20b fixed to the limb 20b of theyoke Mar, and effect a step movement of the stop carriage to the left(Fig. 2), which process will not be further described here, as this isgenerally known. In the following, solely for the sake of completeness,the shift lock, 20A, will be described.

By means of the screws, 20B, (Figs. 3, 8 and 9) a plate, 200, is securedto the machine frame, which is rearwardly bent at its free end, and isprovided with two lateral downwardly projecting U-shaped limbs, 20D. Inthreaded holes, not shown, provided in the limbs, 20D, screws, 20E, areinserted, around the points of which the part, 20G, carrying the fixedshift-tooth, 20F, is swingably mounted by means of its upwardly bentlugs, 20H. The spring, 20y, which at one of its ends is connected to thepart, 2llI,

of thepart, 20G, and at its other end is conneoted to the part, 20C,acts on the part, 20G, in the anticlockwise direction around the screws,20E, (Fig. 9), whereby the part, 20G, presses upwards against the screw,20K, of the part, 20C, and the normal position of the part, 20G, isthereby determined. The projection, 20L, of the part, 20G, isconstructed like a tooth, and this tooth, 20F, coacts with the teeth,20M, (Fig. 8) of the rack, 20N, fixed to the stop carriage, 15. By meansof the screw, 2UP, a lever, 20Q, is swingably mounted on the part, 20G.The pin, 20R, (Fig. 8) provided on the part, 20G, projects through anelongated hole, 208, of the lever, HQ. The spring, 20V, which isconnected to the pin, 20T, of the part, 20G, and to the pin, 20a, of thelever, ZUQ, acts on the lever, 2DQ, round its axis, 2UP, in theanticlockwise direction, so that the lcver,-20Q, rests with its face,20W, formed by one end of the elongated hole, 208, against the pin, 20R,provided on the part, 20G, whereby the normal position of the lever,20Q, is determined; On

The

the lever, HQ, 8. lug, 202, is upwardly bent, which lug co-acts with alever to be later described.

At the point, 209, a two-armed lever, Mn, is jointed to the part, 206),to a limb of which a spring, 20k, is attached, which, with its other endis connected to the lever, ZOQ, and acts upon the two-armed lever, 20h,in the clockwise direction. The forwardly directed limb of this lever isprovided with a projection, 20m, (Fig. 8), with which it can co-act withthe projection, 202, of the lever, ZOQ. The rearwardly projectingtooth-like end, 20:), of the lever, 20h, is in engagement with theteeth, 20M, of the rack, ZUN, of the stop carriage, l5, and as the stopcarriage, I5, is acted upon in the direction of the arrow, M, indicatedin Fig. 8, by a spring, which is not represented, the lever, 20h, restswith its projection, 201, against a lug, ZUQa, bent on the lever, 20Q,whereby the lever, ZDQ, is again acted upon round the axis, 2UP, in theanti-clockwise direction and rests with the face, 20W, of its elongatedhole, 208, against the pin, 20R. whereby the normal position of theparts, 20Q, 20h, is determined.

follows:

On depression of a key I, the rear end 16 '(Figs. 3 and 13) of its keylever l4 sets a stop in the stop carriage l5. At the same time the yoke20:: (Fig. 13) is rocked upwards round its screws 20a and 2|a., Thereby,the lever 20b, fixed to the yoke 20x raises the part 20G, which isrocked clockwise (viewed in Fig. 9) round the screws 20E against theaction of the spring 201 As a result, the loose dog 20p, 20h disengagesthe teeth 20M of the rack 20N of the stop carriage whereas the obliqueface of the fixed dog 20F engages the same as shown in Fig. 8a.Consequently, the loose dog 20p, 2011 is rocked clockwise (Fig. 8) bymeans of its spring 20k, which movement is arrested by the lug 202 ofthe part ZDQ. As a result, the tooth 20 of the loose dog is now justover the next tooth space of the rack 20N. As soon as the depressed keyI is released, the spring 20y (Fig. 9) restores the part 20G to its restposition. Thereby the fixed dog 20F releases the rack ZON and the tooth20p of the loose dog enters the tooth space, lying opposite to it. Bymeans of the stop carriage spring (not shown), the stop carriageis urgedin the direction M (Fig. 8) until the loose dog 20p, 20h impinges withits part 201' against the lug ZOQa. Thus the stop carriage is displacedone step in the direction of the arrow M (Fig. 8).

v In the return of the stop carriage, 15, into its initial position asrepresented in Fig. 2, the teeth, 20p, of the lever, 20h, slip over theteeth, 20M, of the rack, 20N, of the stop carriage, l5, whereby thelever, 2071., is swung round the point, 20g, in the clockwise direction,which takes place quite freely, as in this swinging movement of thelever, 2071, the lever, ZUQ, is also swung against the action of thespring, 20V, round the point, 20?, in consequence of the action of theprojection, 20m, of the lever, 20h, on the lug, 202, of the lever, ZIJQ.

Printing mechanism the two printing mechanism frame walls arranged inthe machine, of which in Fig. 4, however, only the right one is visible.

Between the two printing mechanism frame walls,

The operation of the escapement is briefly as 34, a part, 36, of angularformationv having both of its free ends bent rearwardly at right anglesis secured by means of the screws, 35, Fig. 4, to the right-handprinting mechanism frame wall, 34,

and is fastened bymeansof screws not shown to a the left-hand printingmechanism frame wall, 34. This part, 36, is provided with as many slots,not shown, as there are printing rods 24. 1

The printing mechanism frame here illustrated is arranged by way ofexample for ten denominational orders. The slots serve as guides fortype printing rods, 24, to be later described in a more detailed manner.The type printing rods are so arranged that the distance between printedfigures in adjacent orders is equal to thedistance of the letters of thetyped text. The angle-shaped part, 36, is still further provided withten holes not shown, from which are hung the springs, 25, (Fig. 4),which at their other ends are connected to the noses, 31, of the typeprinting ,rods, 24, and act upon these rods in the direction of thearrow, D. By means of screws, 38, (Figs. 3 and 4) a part, 39, of angularformation and with its free ends bent forwardly at right angles, isfurther fixed to the right printing mechanism frame wall, 34, and to theleft printing mechanism frame wall, 34, by means of screws not shown.The part, 39, similarly to the part, 36, is provided with ten s1ots,'notshown, which likewise serve as guides for the type printing rods, 24.

Further, in the zone of the lower ends of the type printing rods, 24,and between the two printing mechanism frame walls, 34, (Figs. 3 and 4)a part, 40, of U-shape having both its free ends bent upwards at rightangles, is arranged. This is,

fastened to the right-hand printing mechanism frame'wall, 34, by meansof screws, 42, (Figs. 3 and 4) passing through its bent lug, 41, and' to40 the left-hand printing mechanism frame wall, 34,

which is not shown. The part, 48, is provided with ten slots, not shown,which serve as guides for the type printing rods,'24. The parts, 36, 39,40 and 34, form the printing mechanism frame proper.

On the upper ends of the type printing rods, 24, lugs, 43, (Fig. 4) arebent, so that a number of rectangular shaped recesses are formed, inwhich number types, 44, are slidably arranged. In Fig. 4, the coverplateis omitted in order to render the number types, 44, visible. Thenumber types, 44, which on their rearwardly directed ends, carry thetypes, 45, are provided with projections, 46 and 41,

.(Fig. 4). By means .of compression springs, 48,

which on one side rest against the left-hand lugs,

43, of the type printing rods, 24, and on the other side rest againstthe faces of the projections, 46, of the number types, 44, the numbertypes, 44, are held in their rest position, which is determined by thecontact of the right-hand faces, 46a, of,. the number types, 44, againstthe right-hand lugs,

-43, of the type. printing rods, 24.-

On the noses, 49, of the type printing rods, 24, as already described,pins, 26, (Figs. 3 and 4) are riveted, which are embraced by fork-shapedarms,

50, of the driving sectors, 29, swingable around the shaft, 51.

Difleremiial mechanism 4 The driving sectors, 29, under the pull of the'springs, 25, attached to the type printing rods, 24,

'rest with their parts, 52, against a bar, 53, (Fig. 4), which at itsfree erids is fixed to the angle lever; 54, (in Figs. 3 and 4 only theright hand angle lever is visible). These two angle'levers which arearranged to the right and left of the driving sectors, 29, are swingablymounted on the shaft, 51. By means of springs, 55, which on the one sideare connected to the angle levers, 54, and on the other side to pins,55a, provided on the machine frame, the levers, 54, are acted upon inthe clockwise direction. These and the bar, 53,- also form a yoke. Oneachof the downwardly directed ends of the angle levers, 54, a roller,56, is provided (in Fig. 4 only the righthand roller is visible), eachof which rests against a cam, 58, fixed on a shaft, 51, (in Figs. 3.and4 only the right-hand cam is represented). By the action of the springs,25, which on the oneside are attached to the nose, 31, of the typeprinting rods, 24, and on the other side to the angle shaped part, 36,as already earlier mentioned, the type printing rods, 24, are acted uponin the direction of the arrow, D, and likewise the parts, 58 and 29. Bythe contact of the parts, 52, of the driving sectors, 29, with the bar,53, and the contact of the roller, 56, of the angle lever, 54, with thecam, 58, the normal position of the parts, 24, 5 8, 29, 53, and 23, isdetermined.

,The driving sectors, 29, (Figs. 3 and 4) are provided with lugs, 59,which co-act with projections, 68, of the three tooth segments, 28, 28a,and 28b,

which are swingably mounted at the points, 61, on the driving sectors,29.. By means of the springs, 62, which on one side are connected to alever arm, 63, Fig. 5 of each of the toothed segments, 28, 28a, and 28b,and on the other side to the lugs, 64, of the driving sectors, 29,normally the toothedfsegments, 28, 28a, and 28b, are held with theirprojections, 60, in contact with the lugs, 59, of the driving sectors,provided that the driving sectors 29 are rotated in the oppositedirection of the arrow 0. If however, the driving sectors 28 are intheir rest position as represented in Fig. 5, the tooth segments 28, 28aand 28b are held against the action of their springs 62 by means oftheir tens transferlevers 88, 61, 68.

Tens transfer structed as in Fig. 5, are swingably mounted. On

each of the limbs, 61a and 68a, two noses, 69 and 10, are provided,which co-act with the tens. earns, 15, on the toothed Wheels, 1| and 12,of the one totalizer and with the tens cams, 15, on the'toothed wheels,13 and 14, of the other totalizer.

Further, on the shafts, 16and 11, fixed in the machine frame, pawls, 18and 19, formed as in Fig. 5, are swingably mounted, which can co-act.with the small levers, 61 and 68. By means of the springs, 83 and 84,which on the one side are connected to the noses, 80, of the small,levers, 61 and 68, and on the other sideto the noses, 8|, of the pawls,18 and 19, the pawls, 18 and 19, are held with the levers, 61 and 68, inthe normal position as represented in Fig. 5.

The pawis, 86, which are swingably'mounted on the shaft, 85, and co-actwith the angle levers, 88, swingably mounted on the shaft, 81, are heldin their rest position as represented in Fig. 5, by the springs, 89. Theupwardly directed limb, 88a, of the two-armed lever 88, co-acts with alever, not shown, which is swingably mounted in the column counter, V,which lever in the patent application Serial No. 555,331 is indicatedby, 80, and is exhaustively described, and which can co-act with thetens shift cam indicated there by, 81.

It may be remarked that the lever, 61 or B8, belonging to number wheels,93, disposed farthest to the right of the cross totalizer, Q, and, 99,of the cross totalizer, QI, are bent so far to the left that the sameare able to co-act with the pawls, 18 or 19, following on the left, andso forth which on the following grounds must be the case. If for examplethe value v8 is registered in the number wheel, 93, farthest to theright of the cross totalizer, Q, and if the value 4 is to be added, inorder to obtain a correct result, a tens transfer must take place, whichis effected as follows: In the instant in which the number wheel, 93,farthest to the right rotates from 9 to 0, the cam 15, of the toothedwheel, ll, of the cross totalizer, Q, acts on the nose, 99, of thelever, 61, and swings it against the action of the spring, 83, round itsaxis, 65, in the clockwise direction, out of the position represented inFig. 5, whereby the pawl, 18, following on the left which lies in oneplane with the second number wheel, 93, from the right, is swung underthe pull of the spring, 83, so that the nose, 7871, of the pawl, 18,springs into the step, 611', of the lever, 67, and holds this inposition, so that in the swinging of the corresponding toothed segment,28a, this does not push with its part, 28x, against the nose, 83p, andin this manner a further swinging movement of the toothed segment 28a ofone unit in anti-clockwise direction will be released. In the swingingof the driving sectors, 29, and of the toothed segments, 28a, thetoothed segment which cannot be held by the pawl, 73, further rotatesthe toothed wheel, ll, of the second place from the right of the crosstotalizer, Q, through one division, so that the number wheel, 93, isrotated from 0 to l, and a tens transfer has thus taken place.termination of this process, the roller l3! drops into the lower partHill of the cam ISIA under the action of the spring I40, acting on thearm H3211, whereby the arms I321), I320, l32cl are swung in theanti-clockwise direction around the shaft 5i. With this, the part, I35,of the arm, 21320, of the lever, I32, acts on the nose, 136, of thepawl, 79, and swings this in the clockwise direction, whereby the nose,1811, moves out of the step, 67, of the lever, 61, so that the lever,61, under the pull of the spring, 83, can again return into its restposition represented in Fig. 5. However, the lever 61 does notimmediately return to its rest position, but rests with its nose 833) onthe nose 281' of the segment 28a. After the releasing movement of thelever 61 by the pawl 18 has taken place, the raised part |39h of the caml3lA acts on the roller I3 I whereby the arms I321), I320 and |32d arerotated in clockwise direction. During this rotation the segment 28a isreturned to its rest position, in which the nose 83p of the lever 61falls behind the nose 281' of segment 2812, holding it thus in itsnormal position, as illustrated in Fig. 5.

Totalizer operation The teeth 92 of the toothed segments 28 engage thetoothed wheels designated at 9lh in the accompanying drawings as well asin the former U. S. application Sr. No. 555,331, whereby in the swingingof the toothed segments 28 the value is registered in the columncounters V in the additive or subtractive sense.

The toothed segments 28a may engage with the toothed wheels "II or 12according to whether the cross totalizer Q is set for addition or forsub- On the traction. If the toothed wheels, H, are in engagement withthe teeth of the toothed segments, 28a, in the operation of the machine,the toothed wheels, H, are acted upon by the tootl' ed segments, 28a, inthe direction of the arrow, a, and the number wheels, 93, rotated in thepositive sense through the toothed wheels, 12 and 94, and 94a. If, onthe contrary, the toothed wheels, 72, are in engagement with the teethof the toothed segments, 28a, the number wheels, 93, are acted uponthrough the toothed wheels, 94 and 94a, in the negative sense, thereforeopposite to the direction of the arrow, 1), indicated in Fig. 5.

Totalizer shifting To the left of the cross totalizer, Q, which isslidably arranged on the shaft, 99, fixed in the right-hand side wall,95, of the machine frame, (Fig. l) a sleeve, 96?), provided with a ringgroove, 96a, is arranged, into which ring groove, 95a, projects the forkshaped end of a slide, 9'1, displaceably arranged on the front wall ofthe machine. The slide, 97, is provided with a knob, 98, by means ofwhich the displacement of the cross totalizer, Q, to the right or to theleft, on the shaft, 96, can be effected.

If the cross totalizer, Q], is to operate in the positive sense therotational direction corresponding to which is indicated by the arrow,the toothed wheels, 73, will engage with the teeth of the toothedsegments, 28b, and if the cross totalizer, Qi, is to operate in thenegative sense the toothed wheels, 14, will engage with the toothedsegments, 28?).

In order to effect a displacement of the totalizer, Qi, to the right, asleeve, not shown, having a ring groove, is provided on the left of thelefthand side wall, I90, (Fig. 3) of the totalizer, Ql, which sleevelikewise is displaceable with the cross totalizer, Qi, on the shaft,19h. With the ring groove of the sleeve, the fork-shaped end of a slide,H12, engages which is displaceable in the front wall of the machine andits end which projects from the front wall of the machine is providedwith a knob, I03, by means of which a displacement by hand of the cross'totalizer, Ql, is rendered possible to the right or to the left. Thecross totalizers, Q and Ql, which are mounted on bearings on the addingmachine, are displaceably arranged in order to enable multiplication tobe performed by them in a. simple manner.

Cam arrangement for "totalizer engagement. control For controlling theengagement of the totalizers Q and Q! with their actuating racks, thefollowing arrangement is provided. On the shaft 51' two sleeves I28 and57a are slidably but nonrotatably mounted. On each of the sleeves I28and 57a there are fixed three cams. The cams H to H3 are provided forthe totalizer Ql and I the cams Illa to 113a for the totalizer Q. The

4x, the sleeve I28 is provided with a knob- I90.

, Furthermore, a pointer I29 is rotatable on the sleeve I28 but somounted as to be axially displaceable therewith. The pointer I29 is.held against rotation by its embracing the part I29a displaying thedifferent positions D (neutral) T (Total) ST (subtotal) 'of the camseriesinwhich positions the sleeve I28 may be held by any suitablemeans.

The cam series IIIa to 9a is displaced by the following means. Thesleeve 51a. having a ring groove 51b engaged by pins 510 fixed on avertical arm of an angle lever 51d slidably mounted on the frame. Theend of the horizontal arm of the angle lever 51d projecting from theleft hand side wall of the machine is provided with a handle 51c and apointer 51 coacting with the marks D, F, St (Fig. 1) for the pointerI29. Similar means as for the sleeve I28 are provided for the anglelever 51d for holding it in the diiierent positions of adjustment.

Totalizer engagement control this case, the pointer51f has to be set tod."

, Furthermore the lever, I04, by means of the knob,

I04a, (Figs. 1 and 3) is moved from the neutral, (D), to addition, (A),whereby the same is acted upon in the clockwise direction, round itsaxis I05, and the connecting rod, I06, jointed to its rearwardlydirected free limb, I05a, is moved in the direction of the arrow, 0. Therod I06 then swings the lever, I01, around its axis, I08, in theanti-clockwise direction, whereby the pin, I09, provided on the sidewall, 952:, of the totalizer, Q is embraced by the recess, IIII, of thelever, I01. The swinging of the lever I01 about the axis I08 is possiblebecause the guide slot of the angle shaped guiding bracket shown abovethe connecting point of I06 and I01, is wide enough in order to permitsuch swinging movement of the lever I01. If now the hand crank or themotor key, 22, is operated, the driving shaft, 51, is retated in thedirection of the arrow, d, so that the cam II3u. can act on the anglelever II4 thereby controlling the totalizer Q for addition, that is tosay the totalizer Q is rocked round the shaft 96 in the anti-clockwisedirection, whereby the toothed wheels 1I engage with the toothedsegments 29a on their return movement.

If on the contrary, a value is to be registered in the totalizer, Q, inthe negative sense, it is only necessary to set the lever, I04, atsubtraction, whereby the lever, I04, is swung in the anti-' clockwisedirection and the connecting rod I06, correspondingly moved intheopposite direction to that of the arrow c. The lever, I01, is therebyacted upon in the clockwise direction around the point, I08, whereby thepin, II5, provided on the side wall, 95. of the totalizer, Q, isembraced. by the recess, II6, of the lever, I01. If now the lever, I01,in consequence of the rotation of the shaft 51 by the cam II3a throughthe lever H4 is acted upon in the direction of the arrow 6 the toothedwheels 12 of the totalizer Q engage the toothed segments 28a on'theirreturn movement, rotating thereby the number wheels 93 in the negativesense.

I! the lever, I04, is at neutral, D, the parts, I04, I06, and I01,assume the position represented in Fig. 3, whereby on the operation ofthe hand crank or of the motor key, 22, the lever, I01,

' through the parts, 51 and I I3a, as well as throughthe lever, H4, isoperated inthedirection 0! the arrow e, but slides however, inoperativepast the pins, I09, and I I5, of the totalizer, Q, so that this is notdisplaced and no amount can be introduced into the same. By means of alocking pawl, 94A, (Figs. 6 and 7) which is rotatably mounted at thepoints, 943, on the two side walls or the totalizer, Q, (in Fig. 6 onlythe left-hand axis is visible) in the'rest position (represented in fulllines in Figs. 6 and '1) the toothed wheels arranged in totalizer, Q,as'well as the number wheels, 93, are locked, i. e. an unintentionalrotation is thus avoided. In the swinging into the addition position(represented in- Fig. 6 in dotted lines) the projection, 94D, of thelocking pawl, 94A, pushes against -a pin, 94C, fixed in the machineframe, whereby the locking pawl, 94A, 'moves out of engagement with theteeth of the toothed wheels, 94, whilst the toothed wheels, 1 I,simultaneously engage-with the teeth of the toothed segments, 28a. Theprocess in the swing-' ing of the totalizer, Q, into the subtractionposition is similar. In this, however, the swinging of the locking pawl,94A, is effected through striking of the projection, 94D, or the lockingpawl 94A, against the pin, 94H, (Fig. '1) fixed in the machine frame.

The swinging of the. totalizer, QI, for the purpose of introducing avalue in the positive or.

negative sense is efiected by the knob, I I9, of the lever, I20. If thesame is set at addition, A, therefore acted upon round its axis, I2I, inthe clockwise direction so the connecting rod, I23, jointed on one sideto the lever, I20, and on the other side to the lever, I22, swings thelever, I 22, in the anticlockwise direction, whereby the recess, I24, ofthe lever, I22, embraces the pin, I25, which is provided on theleft-hand side wall, I00, of the totalizer QI. v subtraction the cam II3cooperates with the lever I I43 and if now the hand crank or the motorkey 22 is operated, the lever I22 is moved in the direction ,of thearrow f whereby the totalizer, QI, is swung roundthe shaft, IOI, in theanticlockwise direction and thus the toothed wheels, 13, of thetotalizer, QI, are brought into engagement with the teeth of the toothedsegments, 28b,

As in the case of addition and and in the swinging of the toothedsegments 28b,

the number wheels, 99, are actuated in the positive sense. As theintroduction of a value in the negative sense into the totalizer, QI, isobvious from the above description, it will not be here gone intofurther. It may be still remarked that in order to be able to displacethe totalizer, QI, to the right, between thetoothed wheels disposedonthe left-hand side and the left-hand wall of the totalizer, distancepieces 95!; (Fig. 14) are arranged. Besides the right-hand side wall,95a, of the totalizer, Q, and the right-hand side wall, I00a, of thetotalizer, QI, as is evident from Figs.

6, '7 and 3, are formed so small that on a displace-,

, levers, I01 and I22. The setting of the totalizers,

Q and QI, on neutral, total and sub-total is obtained as follows:

On this sleeve 3 cams, III, H2, and H3, are fixed. Furthermore, apointer I29 is rotatably mounted on the sleeve I28 but so as to beaxially displaceable therewith. If the pointer, I29, which is heldagainst rotation by its embracing the part I29a. as shown, points atneutral, D, in which position the lever, I I410, is disposed over thecam, II3, the cam, II3, acts on the lever, 41:, in the second half ofthe revolution of the shaft, 51, whereby the same acts upon the leverI22 in the direction of the arrow f. As a result the toothed wheels 13or the toothed wheels 14 are brought into engagement with the toothedsegments 28b at the beginning of their return movement in the directionof the arrow 9 according to whether the totalizer QI has been set bymeans of the knob I I9 to addition or to subtraction. As soon as thewheels 13 or 14 have engaged the segments 2812, they transfer the amountinto the totalizer QI additively or subtractively.

If by means of the knob I30, the pointer I29 is set for total T, the camH2 is brought into the operative position in relation to. the lever4.1:. As a result, according to whether the knob I I9 has been set toaddition or to subtractionthe wheels 13 or 14 are engaged with thetoothed segments 28b immediately on the operation of the. hand crank ormotor key 22, that is to say, prior to the excursion of the segments 28bin the opposite direction of the arrow 9. Consequently, the amountdisplayed by the number wheels 99, is withdrawn and the number wheelsremain at zero, because the shape of the cam I I2 is such that thewheels 13 or 14 are disengaged with the segments 28b as soon as theyhave completed their excursion in the opposite direction of the arrow 9whereupon they return idly to their rest position.

If now the pointer I29 by means of the knob I30 is set for subtotal ST,the cam II comes into the working position in relation to the lever II43. As a result, according to whether the knob I I9 has been set toaddition or to subtraction, the

wheels 13 or 14 are engaged with the toothed segments 28b alsoimmediately on the operation of the hand crank or motor key 22, just asis the case in total taking. However, the shape of thecam I I I is suchthat the wheels 13 or 14 remain in engagement with the segment 281) bothin their excursion in the opposite direction and in the direction of thearrow 0. Consequently, the amount displayed by the number wheels 99 isleft on the same as is usual in subtotal taking.

For controlling the totalizer Q of the neutral other is provided with asleeve 51a. having a ring cross 51b engaged by bolts 51c fixed on avertical arm of an angle lever 51d slidably inmmted on the frame. Theend of the horizontal arm of the angle lever 51d projecting from thelefthand side wall of the machine is provided with a handle 51c, and apointer 51! coacting with the marks D, T, St (Fig. 10), for the pointerI29.

a4, a shaft, m, (Fig. 4) is' fixed so as to be incapable of rotation. Onthis shaft, I44, angle levers, I45, alternately with a distance ring,not shown, are rotatably mounted. In the machine being described by wayof example, ten angle levers, I45, are arranged.

on the downwardly projecting limb, I46, (Fig. 12) of each of the anglelevers, I45, on each side of the same, a further lever, I41, is jointed.Of the levers, I41, only the left-hand one is visible in Fig. 4. The,levers, I41, are rigidly connected to one another by means of pins, I48and I49, which project through elongated holes, I50, I5I, in verticallyslidable arranged slides, I52. On the left hand levers, I41, noses, I53,are formed, which are so bent that they lie in the plane of the slides,I52. To the noses, I53, springs, I54, are connected, which at theirother end are attached to noses, I55, of the slides, I52. The springs,I54, act upon the levers, I41, and the slides, I52, in such relation toone another, that the faces, I56, and I51, of the elongated holes, I50and I5I, of the slides, I52, rest against the pins, I48 and I49,fastened to the levers, I41, whereby the normal position of the slides,I52, in relation to the levers, I41, is determined. Springs, I58, whichare connected on the one side to the noses, I59, of the slides, I52, andon the other side to an angle shaped part, I60, act upon the slides,I52, together with the levers, I41, in anti-clockwise direction, and inthe direction of the arrow D. The angle-shaped part, I60, is fixed bymeans of screws, I62, which pass through the rectangular downwardly bentlugs, I6I, (in Fig. 4 only the right hand lug is visible) formed on itsfree ends to the two parts of the printing mechanism frame walls, 34.Through the upwardly-acting direction of pull of the springs, I58, theangle levers, I45, are rotated in a clockwise direction round a shaft,I44, and by the contact of their noses, I63, with the bar, I64, are heldin their normal position. The horizontal pull of the springs, I58,acting on the parts, I52 and I41, is later described.

Furthermore, a connecting link I65 (Fig. 4), is jointed on each side ofthe lever I45, between which links at their other free ends levers, I66,are jointed. These are swingably mounted on a shaft, I61, which ismounted in the two side walls, 34, so as to be incapable of rotation,and are guided in slots, not shown, in an angle-shaped comb, I68, whichis fixed to the side walls, 34, by means of the screws, I10, passingthrough the lugs, I69, which are downwardly bent at right angles. InFig. 4 only the right hand fixing is visible. The free upwardly directedends of the lever, I66, formed to correspond-in Fig. 4 act in a mannerto be described later-on the already mentioned number types, 44. Thedownwardly directed free ends, I52a, of the slides, I52, (Fig. 4) areguided in slots of the comb, I1I, according to Fig. 4, not shown, whichat its right-angled upwardly bent lugs, I12, (in Fig. 4 only the right 7is visible) is fastened by means of the screws, 38,

to both of the printing mechanism frame walls whereby yielding of theslides, I52, laterally is avoided.

The slides, I52, are further provided with recesses, I14, (Fig. 4)through which a rod, I15, projects, which rod is fixed by means ofscrews to an angle lever, I11, swingably mounted on the right-handprinting mechanism frame wall, 34, by means of a'screw, I16, and also toan angle lever, I11, swingably mounted by means of a screw, not shown,on the left-hand printing .111, form with the rod, I15, the yoke, I11,I15 and I11. The limbs, I18, which are constructed as shown in Fig. 4,are at their free ends bent at right angles and co-act with the cams,I19, tin Fig. 4 only the right-hand caxn'is visible) on the shaft, 51.

The downwardly directed ends, I52a, (Fig. 4), of the slides, I52, are ofhook-shape. With the recesses, I88, of the same, a bridge, I8I, of'a U-shaped yoke, I82, I8I, I82, can engage. The latter is swingably mountedby means of its limbs, I82, (of whichin Fig. 4 only the right-hand limbis represented) on the shaft, I83, which is mounted so as to benon-rotatable in the supporting frame walls, 34, of the machine. To thedown wardly directed limbs, I84, of the yoke, I82, I8I, I82, two parts,I85, are hired one to each side of each limb.

Between the parts, I85, a roller, .I86, is rotatably mounted, whichco-acts with the cams,

I81, on the driving shaft, 51. To the limbs, I84,

of the yoke, I82, I8I, I82, springs, I88, are connected, which with oneof their ends are attached to the upwardly projecting limbs of the anglelevers, I11, of the yoke, I11, I15, and I11, whereby these and the yoke,I82, I8I, I82, are acted upon in the clockwise direction. Consequentlyas already mentioned, the right-angled bent lower ends ofrthe limbs,I18, of the yoke, I11, I15, I11, rest against the cams, I19, and therollers, I88, arranged in the parts, I85, rest against the cams, I 81,whereby the normal position of the yoke, I11,.I15, and I11, as well asof the yoke, I82, I8I,' and I82, is determined. To the downwardlydirected hook-shaped parts, I52a, of the slides, I52,-noses, I98, (Fig.4) are pressed out, which co-act with stops, I9I, on the two-armedlevers, I92. The levers, I92, are swingably mounted on the shaft, I93,which is mounted so as to be non-rotatable in the two supporting framewalls, 34, of the machine. On the limbs, I94, of the two-armed levers,I92, noses, I95, are formed, which can co-act with the lugs, I98, formedon the driving segments, 29.

Automatic zero printing In order to print the zeros to the right of anumber, the following arrangement'is provided.

On the levers, I92 are lugs, I91, (Fig. 4) which are bent to the left,so that the lug, I91, on the lever, I92, disposed furthest to-the right,rests on the face, I98, of the lever, I92, next to the left, the-lug,I91, of this lever againrests on the lever, I92, lying next to it on theleft and so forth.

Springs, I99, (Fig. 4), which on one side are attached to the limbs,I94, of the levers, I92, and onthe'other side to pins, 288, fixed in themachine frame, act upon the levers, I92, 'in the anti-clockwisedirection. Through the contact of the noses, I98, of the slides, I52,against the stop faces, I9I, of the levers, I92, by the horizontal pullof the already mentioned springs, I58, the normal position of theslides, I52 is determined. I

The arms, 28I, .of the driving sectors, 29, are

-of fork-shape at their lower ends, and embrace I ing the values, 8 to9, or with the zero flap, 282.

The zero flap, 282, is swingably mounted on a suitable shaft, 283, whichis mounted in any suitable manner on the stop carriage, I5.

, rectangularly upward, and its bent part pro- ,iects upwards through anelongated slot, not shown, in the upper cover plate, 285, of the stopcarriage, I5, and is held in its rest position represented in Fig. 3, bymeans of the spring, 288.

The platen, 33, is mounted in bearings in the carriage frame, 281, ofthe typewriter machine, 2, which frame is mounted on the rear carriagerail, 288, and on the front carriage rail, 289, in a known manner, andis held against a. carriage draw spring, not shown; acting in adirection of the arrow, A, by means of the known escapement mechanism,2I8, of the typewriter machine in the required position.

Operation of the printing and impression mechanism sectors 29 may rotateuntil the noses 32 of the feelers 23- impinge against the upwardlyprojecting limb of the zero flap 282. Fr'om'an inspection of Fig. 4, itwill be evident that during this short rocking movement of the sectors29, their lugs I96 are not able to act on the noses I95 of the leversI92. Consequently, no actuation of the impression mechanism may takeplace; If, however, in the two left hand stop rows of the stop carriagestops have been set which correspond to higher values than zero, thestop carriage I5 has moved two steps to the left (as viewed in Fig. 21).Accordingly, the two right hand feelers 23. are free for movement, sincethe zero flap 282 which together with the stop carriage moved also twosteps to the left is no longer in their path of movement;

If now the machine is operated, the two right hand sectors 29 are rockedthrough a greater angle than the remaining sectors. lugs I98 of the tworight hand sectors 29 rock the appertaining levers I92 in the clockwisedirection, thereby releasing the lugs I98 of the two right hand slidesI52 which by means of their springs I 58 are rocked in the anti-clockwise direction until arrested by the rod-I15 of the yoke I11, I15, I11.Thus, the recesses I88 of the two right hand slides I52 lie just beneaththe bridge I8I of the U-shaped yoke I82, I8I, I82. As soon as the latteris rocked in the anti-clockwise direction by means of the cams I81, thetwo right hand slides I52 are drawn downwards through the intermediaryof the bridge I8I of the yoke I82, I8I, I82. As a result, the togglejoint I45, I is stretched, according to which 'the appertaining layersI86 are urged against the types 44 which through the intermediary of thesectors 29 and the type bars 24 have been brought infront of the upperends of the levers I88. Provided that a plurality of paper sheets arebetween the platen 33 and the types 44 owing Hence, the.

earlier in their downward movement, the slides I52 move in relation tothe levers I41 thereby stretching the springs I54.

After the cams I81 have released the yoke I82, I8I, I82, the same isrocked anti-clockwise by means of the springs I88, releasing the slidesI52 which through the intermediary of the springs I58 are drawn upwards.Thus, the levers I45, I65 and IE6 are restored to their rest position.Shortly prior to the completion of the revolution of the shaft 51, thecams I19 act on the yoke I11, I15, I11. Consequently, the latter. isrocked anti-clockwise, whereby the rod I15 of the same swings the tworight hand slides I52 anti-clockwise so that the levers I92, after thereturn of the sectors 29 to their rest position, may fall in front ofthe lugs I90 of the slides I52, thus locking the slides in their restposition. The

- sectors 29 are returned to their rest position by the cams 58 throughthe intermediary of the yoke 54, 53, 54.

On a rail, 2II, fixed to the paper carriage of the typewriting machine,any desired number of column counters, V, are mounted so as to bereadily attached and detached, in order that their positionlongitudinally of the rail, 2, may be arranged to correspond to thecolumn work to be performed.

The column counters, V, attached to the carrying rail, 2, correspond tothose described in patent application Serial No. 555,331, and may be setto each type of calculation.

It may be here remarked that the column counters or totalizers, V, andthe totalizers, Q and QI, mounted on the adding machine are so arrangedin relation to one another that they can be operated together by one andthe same. driving sectors, '29, whereby the whole arrangement isconstructed in an extremely simple manner and the totalizers and typingtext on the platen, 33, may be readily inspected.

If, for example, the amount of 32535, registered in the totalizer Q isto be transferred hundredi'old to the totalizer QI, first of all, thetotalizer QI, which at that time is in its zero condition, is displacedthrough two places to the right (as illustrated inFig. 3a). for thetotalizer Q, is setto addition, that is on mark A (Fig. '1). Theknob-51c (Fig. 111) is now displaced in the direction of the arrow Auntil the pointer 51f points to the mark T (total) whereby the total isbrought opposite the lever Ill, connected to rod I01 (Fig. 3).Furthermore, the knob 9 for totalizer QI. is also set to addition, thatis to mark A (Fig. 1) and the knob' I30 (Fig. 11) is pulled out in theopposite direction to arrow A until the pointer I29 points to mark D(Fig. 10) whereby the cam 3 (Fig. 11) is opposite the lever 4m,connected to rod I22 (Fig. 3).

If now the machine is operated, cam II2a rocks the lever III clockwise,whereby the rod I01 is displaced in the direction of the arrow e. Sincethe knob I 04a has been set to addition, the recess II 0 of rod I01 hasengaged the pin I09 of the totalizer Q. As a result, the totalizer Q, bythe displacement of the rod I01 in the direction of the arrow e will berocked anti-clockwise so that the wheels 1| come into engagement withthe segments 28a. It now, while the machine is operated, the sectors 29are rocked clockwise, the segments 28a turn the wheels H and, throughthe intermediaryof the wheels 12 and 94, the numeral wheels back to zerowhich zero position is brought about by the abutment of the noses 15Thereupon, knob I0la v totalizer Q.

of the wheels 1I against the noses 69 of the tens transfer levers 61which for this purpose have been locked in their rest position by anysuitable locking rod (not shown), preventing the levers 01 from rockingin the clockwise direction.

Accordingly, the segments 281), by means of the sectors 29 are rockedthrough the same amounts as the segments 28a. Now, by means of the camII3, the lever H41: is rocked clockwise, whereby the rod I22 isdisplaced in the direction of the arrow 1. As a result, the totalizerQI, through the engagement of the recess I24 of the rod I22 with the pinI25,'is rocked anti-clockwise, so that the wheels 13 of the totalizer QIwill come into engagement with the segments 282). At the same time, thecam II 2a has turned so far, that the lever I I4, by means of a spring(not shown) is rocked anti-clockwise, whereby the totalizer Q, throughthe intermediary of rod I01 is rocked out of engagement with thesegments 28a.

If now, the sectors 29 are rocked anti-clockwise to their initialposition, the amount of 32535 will be added into the third to theseventh decimal place from the right of totalizer QI. Therefore, thetotalizer QI shows now the amount 3253500 on account of the fact thatthe units and the tenths place of the same have not been afiected.

Now, it may be assumed that the totalizer QI is held in its displacedposition by two decimal places to the right and that in the units and Itenths position, there are figures other than zero.

If now, a total is taken from the totalizer QI and transferred to thetotalizer Q it is obvious that the figures of the units and tenthsplaces of the totalizer QI are not transferred, since no segments 28bare opposite these decimal places. Accordingly superfluous places arecancelled while transferring from one totalizer to another although thecancelled figures remain stored in the totalizer from which the total istaken.

By forming the totalizer Q as double totalizer Q, Q, it is possible tostore amounts for later application. For this purpose, the doubletotalizer Q, Q is displaced so far to the right that the units place orthe totalizer Q is opposite the right hand sector 29. Any amount maythen be transferred from the totalizer QI to the If then the doubletotalizer is brought back to the position illustrated in Fig. 3a., theamount in the totalizer Q remains unaffected.

In a similar manner the totalizer QI or both of the totalizers Q and QImay be constructed as double totalizers.
